W. H. HUTCHINS ENG I NE 5 TARTER Filed Nov. 2, 1916 of the motionless fiy-wheel, the spring 17 yields and permits the armature to continue rotation and momentarily to overrun the drive-shaft, until the force transmitted through the pinion has started the fly-wheel into motion.

It willbe apparent, that b making the head 7 of the culiar fohn s norm, and locating the pinion 11 within this head and within the shaft-bearing supported by it, it is rendered possible to br ng the gearing close to the end of the armature, which, in turn makes it possible to mount the motor casing upon the fiy-wheel housing with the centre of gravity of the motor so close to the housing that the motor may be supported entirely upon the housing without the necessity of additional braces or supports.

While a spring has been disclosed as the means of connection between the armatureshaft and the driveshaft, it will be apparcut that the invention is not limited tothis particular form. and also that the particular form of geariu described for connecting the drive-shaft an the engine is not'an cmential feature of the invention,

The invention claimed is:-

i. In a starting motor unit, in combination, a rotor having a shaft. a casing for said rotor carrying-bearings for said shaft, and a driving member for an engine connected to be driven from said shaft and' mounted between said rotor and the bearing nearest thereto on one side thereof.

2.. In a starting motor unit, in combina-- said shaft and disposed between said rotor and the proximate bearing on one side thereof.

3. In apparatus of the r-lass described, in

combination, a starting motor, having a "shaft, a. yoke and a head, said shaft projecting beyond said yoke at the end remote from the head, an automatic engine startin dr1ve,- threaded on the nrojectin end of sai shaft, and a housing for said rive, havin a part secured with respect to said yoke, an

said motor on a non-rotating part associate with'said engine, at a point between said bearings.

5. 'Inapparatus of the class described, in combination, an engine leg, 0. starting motor, heads for Faid motor, having bearings, an engine starting drive between said bearings and extending within one of said heads, and a flange on said motor, near the center of inertia thereof, secured around an opening' in said leg, said motor being unsupporte at its ends.

6. In apparatus of the class described, in

combination, an engine leg, a starting motor having a shaft, heads for said motor, one

of said heads-being cup-shaped, bearings for said shaft near theouter ends of said heads,

an'automatic engine starting drive threaded on said shaft and extending through said cupshapcd head and a flange rigid with respect to said cup-shaped head, at a point spaced'from its outer end and near the cen-' ter of inertia ofsaid motor, and secured to said engine leg, said motor being unsupported at its ends.

T. In apparatus of the class described, in

combination, a motor, heads for said motor, one-of said heads being cup-shaped, a. driv-.

ing connection'for an en ine, disposed in said cup-shaped head, an means for supporting said-motor on a non-rotating part associated with said engine, at a plane near the center of inertia of said motor.
